7.6 - Transfer Between KE & GPE

• The key concepts you need to understand are:

  • As an object rises, KE is converted to GPE
  • As an object falls, GPE is converted to KE 
  • KE lost = GPE gained and KE gained = GPE lost
• As a ball falls through the air, energy is transferred from the ball's gravitational potential energy store to its kinetic energy store. The energy is transferred between the two energy stores via mechanical energy transfer.
